Crystal Palace National Sports Centre has been host to an impressive sporting heritage since it opened in 1964. However, the facilities of the Grade II Listed Centre have seen better days and change is needed to keep the Centre running. In 2018 we began work for the Mayor of London, as part of a team of architects, designers, enthusiasts and specialists tasked with coming up with a plan for the future of the Centre. Our first step was establishing that this project was different from consultations that had come before. The Centre benefits from an active and engaged group of users and supporters, however a number of consultation processes had taken place in the near past, and there was a sense both of mistrust, and that this project too would not result in change. We created the On Your Marks brand strategically - choosing a palette made up of colours found in the centre - and used playful sporting language to both galvanise the public into action and to spark an interest in the project. We asked the Centre’s users to coach us - recognising their knowledge, expertise, and their personal desire to do the best for their community. We held a series of workshop events, inviting people to share their insider knowledge and to help shape the brief for the team architects, Hawkins\Brown, to respond to. Alongside engaging existing users of the Centre, we focussed our efforts upon capturing the attention of prospective future users. We wanted to capture the attention of local people who might not otherwise have had their voices heard. We created a digital questionnaire which was promoted extensively online to people living and working within the local area, receiving over 1,500 responses. The Community Conference was the final public event as part of the On Your Marks! engagement programme, showcasing developed design studies, building on previous consultation stages, and offering the public and Centre users an opportunity to understand how their feedback had shaped the project team’s development of a future proposal.
